I have to re-bind every time I use my spektrum/xps, it works fine until I shut it off, re-bind every time...
Similar problems with the Airtronics FHSS system and the Duratrax ESC7500. I had to re-bind the Rx every time and the ESC would be setup.....til I had a crash that flipped my switch off.....someone on the track flipped it back, it shot out of their hands at full speed, bounced off of one wall and then ran straight into a Tek18 at full speed.
